In-N-Out's famous yellow arrow sign can easily be seen from Highway 101. Naturally, the owner of McDonald's wanted his golden arches also visible from Highway 101's overpass to alert drivers that burgers are nearby.

In-N-Out owns the giant, strategically located signpost, and initially there was some hesitation from owners whether they would share space with a direct competitor.

"We need the sign," said Raymond Costa, owner of the new McDonald's. "We put balloons up to let people know we're here. We haven't got our highway sign up yet, so it's mostly local customers."

The owners were able to come to an agreement, and Costa expects arches to go up within the next month.

KSBW asked its Facebook fans which burger is better: the Big Mac or Double Double? Out of 195 responses, the vast majority said the Double Double is far superior to the Big Mac because of its taste and quality of meat.
